This 12-volt starter relay (solenoid) from DB Electrical is built to match OEM fit and function for a wide range of Yamaha jet boats and watercraft from model years 2005 through 2019.

Before ordering, verify your OEM number or vehicle compatibility list to confirm correct fitment.

How does this solenoid restore starting performance?

When a starter relay fails, the starter may not receive full battery power and the engine won’t crank. Replacing a worn or corroded relay with this DB Electrical unit re-establishes a direct, low-resistance path for starting current, helping the starter engage reliably. It’s especially helpful if the original relay shows heat damage, pitting, or intermittent operation.

• 12 V rating compatible with original electrical system.
